Keyboard navigation

[boxed]

This is a first rough draft for keyboard navigation support. I'd like some feedback on what kind of changes you'd suggest before merging.

I'd like to eventually incorporate this into my media center (https://github.com/boxed/cmi), where remote control navigation is mapped to keyboard operations. But I think something like this would be useful to other people too.

Hi @boxed, the keyboard nav is pretty cool :)

Wondering what other use cases are there for this, or what would be an abstract behavior. You'd have to map some sort of "enter" event on a focus element, to be transmitted to the contained widget. It gets a bit complicated when you have other actions inside each widget (like 1/2/3x resize in our demo), because you'd have to pass along the focus to another level.

Definitely have to try your media center, XBMC started giving me headaches :)

Thanks!

In the case of CMi I just have big tiles that have a single action on them, so it's not a problem in my case. In the demo case I think it's more reasonable to map other keyboard shortcuts to the other commands. So for example '1' to 1x, '2' to 2x and '3' to 3x.

What is the status of this? It's now a pretty old PR. Still keyboard only support should be considered.

I’d also like to know if this will be merged. I would like to be able to remove my fork if nothing else. It’s cluttering up my profile :P
